Right PHP type for pgsql arrays

[Gerych1984]

Q	A
Is bugfix?	✔️
New feature?	❌
Breaks BC?	✔️

1. Return array as phpType for PgSql *[] columns
2. Allow type cast values in ArrayParser

P.S. maybe move all cast methods on new object? Something like TypeCaster etc. With they can be cast values wo double code

What's wrong with the current type casting?

db-pgsql/src/ColumnSchema.php

Line 85 in 3d47b9a

array_walk_recursive($value, function (?string &$val) {

db-pgsql/src/ColumnSchema.php

Line 107 in 3d47b9a

protected function phpTypecastValue($value)

There's nothing wrong with him. But sometimes you need to use it outside of schema/AR (for example in console command where you need to go through > 100000 rows, to reduce memory consumption). And in this case you have to cast it separately to php-type, because by default it returns array of strings. So as idea do it something like

$array = (new ArrayParser)->asInt()->parse($row['array_column'])

Instead of

$parsed = (new ArrayParser)->parse($row['array_column']);

$array = /* some double code do parse it as int array*/

I suppose you should use your own implementation of ArrayParser for these tasks in your project.
